BACKGROUND: Acute kidney injury (AKI) is a potential complication after restricted fluid therapy for major surgery. The aim of this study was to evaluate the incidence of AKI for living liver donor hepatectomy in which applied intraoperative protocolized fluid restriction was used targeting a low central venous pressure (CVP) level with high pulse pressure variation (PPV) and systolic pressure variation (SPV).
MATERIAL AND METHODS: Living liver donors were admitted for this retrospective observational study. Low CVP <5 mm Hg with high PPV<20% and SPV<15% were the targets of the clinical protocol to reduce intraoperative blood loss via protocolized fluid management until the end of the hepatic parenchymal division. KDIGO criteria were used for AKI definition. The SPSS version 11.5 program was used for statistical analysis.
RESULTS: The study included 130 patients, 79 (60.8%) men and 51 (39.2%) women, with from 18 to 58 years of age. Donors underwent right and left lobe hepatectomies (116 and 14, respectively). The baseline CVP, the lowest CVP of hepatectomy, and the highest CVP measured after hepatectomy were 7.45 ± 2.41, 4.28 ± 1.12, 7.67 ± 2.09 mm Hg, respectively. Only 4 patients with right lobe hepatectomy developed AKI stage I (3.1%) in the first 24 hours. The 4 patients were recovered at 48 hours postoperatively.
CONCLUSION: This study demonstrated that a CVP target of <5 mm Hg and high PPV/SPV via a simple fluid management modality with protocolized-fluid restriction until the procurement may not cause AKI in living liver donors in a closed follow-up anesthesia approach.
